I applied a patch for associating user data to text segments in the
text widget a couple of month ago, but not much has happened with it
since.  It was an ugly hack really, but I haven't had the time to work
more with it since...work and studies is taking up most of my time for
the moment.

I use it in an editor widget (a subclass of the text widget), but as
you point out there's a lot of useful things you can do with such
data, so it really belongs in the text widget.

I only use it for highlighting at the moment, but I have some other
plans for it as well.  Bookmarks is one thing, another is the
possibility of "hiding" and "showing" text with double clicks like
emacs' outline mode...or "links" from variables and functions use to
there definition...stuff like that.

You can take a look at what I've done at

   <URL:http://www.daimi.au.dk/~mailund/gtk.html>

I'm in the middle of rewriting the highlighting, but I'm working
*very* slowly right now, 'cause I'm overworked with a lot of other
stuff.  I could use all the help I can get...so if you're interested
let me know.
